What's Happening?
Researchers at the University of Michigan have created a groundbreaking semiconductor device that utilizes laser light to direct the movement of electrons without the need for an applied electric field. This innovative device, described as an 'electron
lighthouse,' was developed to explore fundamental physics and demonstrate a previously unobserved behavior. The research, supported by the U.S. National Science Foundation, shows that two different colors of light can produce an organized flow of electrons through a semiconductor. By rotating the polarization of the optical fields, the direction of the electron flow can be controlled. This discovery could pave the way for advancements in technologies that integrate optics and electronics, such as advanced sensing, imaging, and telecommunications.
